COMBINED ANTENNA SYSTEM

摘要

PURPOSE: A combined antenna system is provided to transmit a signal of different frequency band in a single wire by integrating signals of different frequency band. CONSTITUTION: A first receiver(110) extracts a signal of a first frequency wideband from a frequency signal. A second receiver(210) extracts a signal of a secondary frequency band from a frequency signal. A common node is connected for the output of the single conductor to the output terminal of the first receiver and output terminal of the second receiver. A second receiver comprises a notch filter(220). The notch filter eliminates the signal of the frequency band except for a secondary frequency band. The output terminal of the notch filter is connected to the common node.
